What can cause my temperature gage to fluctuate.
The thermostat gage on my 96 dodge
Cummins goes from 150 to 190
fluctuating up and down. I replaced
the thermostat and the same thing
continues to happen. I have read that
it could be many things including the
injectors if u have a shaky engine. My
engine runs fairly smooth Im certain
the shaking while driving is just
caused by my tires. Any ideas
Purge air out of the system. Sounds like an air bubble to me.
